Slava Shubin
@sviatoslavshubin
Senior Frontend Developer at T1 Group building AI/ML platforms
SerbiaWhat I'm looking for
At T1 Group, I designed and developed a React platform for manual data annotation and ML dataset preparation for VTB Bank. I improved page rendering performance by 20% and implemented virtualization and data-fetching optimizations for large datasets.
On T1 Group’s Label Studio project, I developed snapshot-based exports that let users export large datasets without blocking their work. I also developed APIs for file-operation restrictions using Python frameworks.
At iFellow, I developed the auto-loan application module for Sberbank Online. The work helped reduce the application process from 40 minutes to 15 and contributed to a 31% increase in bank approval rates.
At iFellow, I also designed and developed an internal React and TypeScript design system with 50+ reusable components. Earlier at UTair Group, I developed real-time customer-support chat functionality and improved application rendering performance.
